Like most history, there is conflicting information about Khazaria, where it was, and what actually happened there. Some maps show it further to the east, barely overlapping with the Ukraine at all, and some even claim Tartaria and Khazaria are synonymous, suggesting Khazaria was something like the Russian Federation in terms of it's extent at the verge of prehistory and historical times. There are also various claims that the conversion of the population wasn't complete, forced, or etc. No one really knows what happened ~1000 years ago, do they.

Last I heard ~100k Jews had traveled to the Ukraine for a holiday, and there's some upset from certain circles in the military about it, at least from a video I've seen, that also discussed significant financial considerations. Anyway, I appreciate your elucidation of your thoughts on these matters.

Thanks!

Edit: I've read recently extensive discussions regarding proselytization by Judaism, particularly during the Roman era, and the claim that Xtianity was merely a Jewish sect at that time doing the same thing.

"...which is supposed to be by bloodline."

The recent form of Judaism isn't eternal, and prior to modern times and the Talmud, Judaism was a much different religion, ethnicity, and culture. There are claims that a lot of modern Judaism stemmed from Phoenician religion and culture, due to many Phoenicians joining after the Punic wars ended the Phoenicians and 'Carthago delenda est.'
